The wide application of chlorine disinfectant for drinking water treatment has led to the appearance of chlorine-resistant bacteria, which pose a severe threat to public health. This study was performed to search for the relationship of the presence of bacteria with the purity of drinking water or the relationship between growth of bacteria on efficiency of R.o. water and its effects on the purification of drinking water that used by human in my country , Its serious attempts to find acommon problem and find persuasive solutions.


The samples of raw and RO of drinking water were collected from the study sites , the number of samples were (25) samples before and after Ro in three  replication, finally were collected (10) samples of household  Ro filters from (karkh and Rusafa) as acomparison the best type of efficiency in purification of drinking water.samples were collected in bottles prepared in paragraph 2-1-5 and closed tightly and taken to the laboratory within 2-3 hours in cooling box to conduct the physiochemical tests .

The results of bacteriological tests show that the Ro filter was able to reduce and remove the bacteriological contamination in water and (Ricardo Franci Gonçalves a, Laila de Oliveira Vaz a, Mario Peres a , Solange Sarnaglia Merlo, 2021) and

  Exept some samples that were diagnose as containing bacterial growth from .Several type of bacteria .it shows the Ability of bacteria to to form biofilm in R.O filter( ELSEVIER P Kumar, K Hegde, SK Brar and M Cledon,2020 - Chemical Engineering )

… This experiment provided more information to assess the ability of the bacterial strain to  perhaps because filtes were not replaced and it has became out of date.( EF HaneyMJ TrimbleREW Hancock - Nature Protocols, 2021)
